Microwave Imaging for Soil Characterization

Microwaves are electromagnetic radiation with frequencies between

300 MHz and 300 GHz, corresponding to wavelengths ranging from as

long as one meter to as short as one millimeter. International agreements

regulate the use of the different parts of the microwave spectrum. The

frequencies 915 MHz and 2.45 GHz are the most common among those

dedicated to power applications for Industrial, Scientific, and Medical

purposes.
